Acute and repeated toxicological study of Myelophil, an ethanol extract of a mixture of Astragali Radix and Salviae Miltiorrhizae Radix, in beagle dogs.

BACKGROUND: To evaluate the pharmaceutical safety of Myelophil, an ethanol extract of a mixture of Astragali Radix and Salviae Miltiorrhizae Radix, using both acute and repeated toxicological studies. METHODS: A total of 40 beagle dogs (20 each male and female) were fed doses up to 5,000 mg/kg for the acute study and up to 1,250 mg/kg for the 13-week repeated dose toxicological study. Adverse effects were examined intensively by comparing the differences between normal and drug-administered groups using clinical signs, autopsies, histopathological findings, hematology, urinalysis, and biochemical analysis. RESULTS: No mortality or drug-related clinical signs were observed in the Myelophil-treated groups, except for vomiting due to an excessive dose (5,000 mg/kg). Likewise, in the repeated toxicity test, compound-colored stools in the Myelophil-treated groups and soft stools in all groups, including the control, were observed. No drug-related abnormalities were found in the histopathology, hematology, urinalysis, and biochemical analyses for any doses of Myelophil. CONCLUSION: These results support the safety of Myelophil with a no observed adverse effect level (NOAEL) of 1250 mg/kg in beagle dogs, which corresponds to a human equivalent dose (HED) of 694 g/kg.

Efficacy and safety of acupuncture for functional constipation: a randomised, sham-controlled pilot trial.

BACKGROUND: The prevalence of functional constipation (FC) is 3-27%, and FC has been reported to cause discomfort in daily life and various complications. The treatment for FC depends on laxatives, and thus, effective and non-toxic alternative treatments are needed. METHODS: We conducted a randomised, sham-controlled parallel-design, pilot trial. Participants with FC were randomly assigned to either the real acupuncture (RA) or sham acupuncture (SA) group. The RA consisted of eight fixed acupuncture points (bilateral ST25, ST27, BL52 and BL25) and four additional points targeted to the individual based on Traditional Korean medicine (TKM). SA consisted of shallow acupuncture insertion at 12 non-acupuncture points. Twelve sessions were provided over 4 weeks. The outcome measures were weekly defecation frequency (DF), spontaneous complete bowel movement (SCBM), Bristol stool scale (BSS) score and constipation assessment scale (CAS) score. The participants were followed for 4 weeks after the treatment. RESULTS: Thirty participants were enrolled (15:15). The mean DF were 5.86 ± 5.62, 5.43 ± 3.39 and 5.79 ± 3.64 in the RA group and 3.73 ± 1.62, 5.00 ± 1.77 and 5.40 ± 1.96 in the SA group at weeks 1, 5, and 9, respectively. The increases in weekly SCBMs were 2.50 ± 3.86 and 2.71 ± 4.01 with RA and 2.33 ± 2.74 and 1.93 ± 2.25 with SA at weeks 5 and 9, respectively (mean difference [MD] 0.78). The BSS scores were 0.57 ± 1.72 and 1.09 ± 1.30 with RA and 0.15 ± 1.06 and 0.14 ± 0.88 with SA at weeks 5 and 9, respectively (MD 0.95). The CAS score changes were - 3.21 ± 2.91 and - 3.50 ± 3.98 with RA and - 2.67 + ±2.82 and - 2.87 ± 2.95 with SA at weeks 5 and 9, respectively. Greater improvements were observed in subgroup analysis of participants with hard stool. The numbers of participants who developed adverse events (AEs) were equal in both groups (four in each group), and the AEs were not directly related to the intervention. CONCLUSIONS: This clinical trial shows feasibility with minor modifications to the primary outcome measure and comparator. Acupuncture showed clinically meaningful improvements in terms of SCBMs occurring more than 3 times per week and in these improvements being maintained for 4 weeks after treatment completion. As this is a pilot trial, future studies are warranted to confirm the efficacy and safety. TRIAL REGISTRATION: KCT0000926 (Registered on 14 November 2013).

A nationwide study of the incidence rate of herb-induced liver injury in Korea.

Discrepant incidence has been reported regarding the incidence of herb-induced liver injury (HILI). To address the growing worldwide concern of HILI, we evaluated the risk of HILI in a nationwide prospective study. Between April 2013 and January 2016, 1001 inpatients (360 males and 641 females) from 10 tertiary hospitals throughout South Korea were treated with herbal drugs and had their liver enzymes periodically measured. A total of six patients met the criteria for HILI with RUCAM scores ranging from 4 to 7. All these participants were women and developed the hepatocellular type of HILI. One HILI participant met the criteria for Hy's law; however, none of six cases presented clinical symptoms related to liver injury. This is the first nationwide prospective study that estimated the extent of the incidence of HILI [total: 0.60%, 95% confidence interval (CI) 0.12-1.08; women: 0.95%, 95% CI 0.19-1.68] and described its features in hospitalized participants.

Moxibustion for cancer-related fatigue: study protocol for a randomized controlled trial.

BACKGROUND: Cancer-related fatigue is one of the most common symptoms experienced by cancer patients, and it diminishes their quality of life. However, there is currently no confirmed standard treatment for cancer-related fatigue, and thus, many patients who suffer cancer-related fatigue seek complementary and alternative medicines such as moxibustion. Moxibustion is one of the most popular therapies in traditional Korean medicine used to manage fatigue. Recent studies have also demonstrated that moxibustion is effective for treating chronic fatigue. However, there is insufficient evidence supporting the effect of moxibustion against cancer-related fatigue. The aim of this study is to assess the efficacy and safety of moxibustion treatment for cancer-related fatigue. METHODS/DESIGN: A multi-center, three-armed parallel, randomized controlled trial will be conducted. Ninety-six patients with cancer-related fatigue will be recruited from three clinical research centers. They will be randomly allocated to one of three groups in a 1:1:1 ratio. The moxibustion group will receive moxibustion treatment at CV8, CV12, LI4 and ST36. The sham moxibustion group will receive sham moxibustion at non-acupoints. Both the moxibustion and sham moxibustion groups will receive 30-min treatments twice a week for 8 weeks. The usual care group will not receive moxibustion treatment. All participants will be educated via a brochure on how to manage cancer-related fatigue in daily life. The outcome measurements will be evaluated at baseline, week 5, week 9, and week 13 by assessors who are blinded to the group allocation. The primary outcome measure will be the mean change in the average scores of the Brief Fatigue Inventory before and after treatments between groups. The secondary outcome measures will be the mean difference in changes from baseline of the Brief Fatigue Inventory, functional assessments of cancer therapy-fatigue, European Organization for Research and Treatment of Cancer Quality of Life Questionnaire C-30 scores, and Montreal Cognitive Assessment scores between groups. Safety will be assessed by monitoring adverse events at each visit. DISCUSSION: The results of this study will provide evidence to confirm whether moxibustion can be used as a therapeutic option for treating cancer-related fatigue.

A manual acupuncture treatment attenuates common cold and its symptoms: a case series report from South Korea.

OBJECTIVE: To investigate beneficial effects of manual acupuncture on common cold periods and its symptoms depended on the difference onset time of common cold, within 36 h or over than that. To prove effects of manual acupuncture on common cold, a retrospective chart review was conducted. METHODS: Chart data for patients with common cold who were treated with only manual acupuncture with fulfilling Jackson scales and satisfaction at the end of each treatment were collected via multi-centers of Oriental hospitals, Oriental medicine clinics and covalent hospital in South Korea. Totally 187 patients were divided into two groups, Group Ⅰ (115 patients, within 36 h) and Group Ⅱ (72 patients, onset time of cold over than 36 h). Finally 120 patients were observed until entire resolution of cold symptoms. RESULTS: Group Ⅰ showed significant decreases themediandurationsofcompletelyrecovery (3 days; 95% CI 3.0-4.0) as compared with Group Ⅱ (6 days; 95% CI 4.0-7.0, P < 0.001). The manual acupuncture beneficially worked for reduction rate of common cold symptoms by 50% after initial treatment, decreased cold symptoms, and reduced cold duration. CONCLUSION: Manual acupuncture beneficially affected common cold and its symptoms. Moreover it is more susceptibility on the early time of onset cold.

Efficacy of Moxibustion for Cancer-Related Fatigue in Patients with Breast Cancer: A Systematic Review and Meta-Analysis.

INTRODUCTION: Breast cancer is the most commonly diagnosed cancer worldwide, and most patients experience fatigue. However, there are no effective treatments for cancer-related fatigue (CRF). Several randomized controlled trials (RCTs) have suggested that moxibustion improves CRF. We conducted a systematic review and meta-analysis to compare the differences in fatigue scale scores, quality of life, and clinical efficacy in patients with breast cancer who developed CRF and did versus did not receive moxibustion. METHODS: RCTs were searched in 7 databases using a standardized search method from database inception to March 2023, and RCTs that met the inclusion criteria were selected. RESULTS: Among 1337 initially identified RCTs, 10 RCTs involving 744 participants were selected for this study. The meta-analysis involved assessment of the revised Piper Fatigue Scale scores, Cancer Fatigue Scale scores, Karnofsky Performance Scale scores, Athens Insomnia Scale scores, clinical efficacy, and Qi deficiency syndrome scale scores. Compared with the control, moxibustion was associated with significantly better Piper Fatigue Scale scores (P < 0.0001), quality of life [Karnofsky Performance Scale scores (P < 0.0001)], clinical efficacy (P = 0.0007), and Qi deficiency syndrome scale scores (P = 0.02). CONCLUSIONS: Moxibustion improves CRF in patients with breast cancer. The efficacy of moxibustion should be further examined by high-quality studies in various countries with patients subdivided by their breast cancer treatment status.

Saponin and non-saponin fractions of red ginseng ameliorate cisplatin-induced pica in rats.

CONTEXT: Nausea and vomiting are considered as the foremost unpleasant side effects of chemotherapy experienced by 20-90% of cancer patients. OBJECTIVE: In the present study, the effects of Korean Panax ginseng C.A. Meyer (Araliaceae) (RG), ginseng saponin (GS) and non-saponin (GNS) on cisplatin (CP)-induced pica and gastric damage in rats were investigated. MATERIAL AND METHODS: Rats were treated with RG (25, 50, 100 mg/kg b.wt.), GS (5 and 10 mg/kg 100 mg/kg b.wt.) and GNS (50 and 100 mg/kg b.wt.) before or after a single intraperitoneal injection of CP (6 mg/kg b.wt.). Kaolin together with normal food intake, normal food alone, body weight, histological examination of stomach and small intestine were used as indices of CP-induced pica in rats. RESULTS: Pre-treatment with RG (50 and 100 mg/kg b.wt.) attenuated CP-induced kaolin intake at 24 h. CP-induced kaolin intake decreased upon post-treatment of rats with RG (50 and 100 mg/kg b.wt.) at 48 h. The incidence of body weight reduction at 48 and 72 h diminished in rats post-treated with RG (50 mg/kg b.wt.). Pre-treatment with GS (5 and 10 mg/kg b.wt.) and GNS (50 and 100 mg/kg b.wt.) attenuated CP-induced kaolin intake while normal food intake was not improved in 24 and 48 h. DISCUSSION AND CONCLUSION: The gastro-protective effects of RG, GS and GNS were further confirmed by histopathological (damage in glandular portion and villi with dilated appearance) findings. The study indicates that both the red GS and GNS improve feeding behavior against CP-induced pica in rats.

Adjuvant effect of herbal medicine on transarterial chemoembolization in patients with hepatocellular carcinoma: A systematic review and meta-analysis.

Objectives: Primary hepatocellular carcinoma (HCC) is one of the leading causes of cancer-related deaths, especially in Asian countries. As a practical treatment option, transarterial chemoembolization (TACE) has been well applied; however, its limited efficacy remains challenging. This study analyzed the adjuvant effects of herbal medicine on TACE to determine whether it improves clinical outcomes in patients with HCC. Methods: A systematic review and meta-analysis was performed to compare the adjuvant effects of herbal medicine on TACE versus TACE therapy alone. We searched the literature from eight databases since January 2011. Results: Twenty-five studies involving 2,623 participants were selected. The adjuvant therapy of herbal medicine on TACE improved the overall survival at 0.5 years (OR = 1.70; 95% CI 1.21-2.38), 1 year (OR = 2.01; 95% CI 1.65-2.46), 2 years (OR = 1.83; 95% CI 1.20-2.80), and 3 years (OR = 1.90; 95% CI 1.25-2.91). The combination therapy also increased the tumor response rate (OR = 1.84; 95% CI 1.40-2.42). Conclusions: Despite the unsatisfactory quality of the included studies, the adjuvant therapy of herbal medicine on TACE may provide survival benefits to patients with HCC.

Herbal Medicine Yukgunja-Tang for Functional Dyspepsia: A Protocol for a Randomized, Controlled, Multicenter Clinical Trial.

The herbal medicine Yukgunja-tang has been widely used for the treatment of functional dyspepsia (FD) in the clinical setting of East Asian traditional medicine. This paper presents a protocol for a randomized, assessor-blind, controlled, multicenter, three-arm parallel clinical trial comparing the effectiveness, safety, and cost-effectiveness of Yukgunja-tang with Pyeongwi-san and usual care. A total of 140 participants with Rome IV-diagnosed FD will be randomly assigned to either the Yukgunja-tang (n = 56), Pyeongwi-san (n = 56), or usual care (n = 28) groups. All participants will be educated on dietary guidelines for FD patients. Participants in the Yukgunja-tang and Pyeongwi-san groups will take investigational products for 6 weeks. All participants will be assessed for clinical parameters at weeks 0, 3, 6, 9, and 24. The primary outcome will be measured on the total dyspepsia symptom scale, and the secondary outcome will include the single dyspepsia symptom scale, overall treatment effect, the visual analog scale for dyspepsia, FD-related quality of life, hospital anxiety and depression scale, EuroQol-5 dimension, pattern identification, and serum levels of acyl-ghrelin and deacyl-ghrelin. Adverse events and laboratory tests will be monitored for safety assessment. The results will provide evidence of the effectiveness, safety, and cost-effectiveness of Yukgunja-tang in the treatment of FD.

Characteristics of insulin resistance in Korean adults from the perspective of circadian and metabolic sensing genes.

BACKGROUND: The biological clock allows an organism to anticipate periodic environmental changes and adjust its physiology and behavior accordingly. OBJECTIVE: This retrospective cross-sectional study examined circadian gene polymorphisms and clinical characteristics associated with insulin resistance (IR). METHODS: We analyzed data from 1,404 Korean adults aged 30 to 55 with no history of cancer and cardio-cerebrovascular disease. The population was classified according to sex and homeostasis model assessment of insulin resistance (HOMA-IR) values. Demographics, anthropometric and clinical characteristics, and single nucleotide polymorphisms (SNPs) were analyzed with respect to sex, age, and HOMA-IR values. We used association rule mining to identify sets of SNPs from circadian and metabolic sensing genes that may be associated with IR. RESULTS: Among the subjects, 15.0% of 960 women and 24.3% of 444 men had HOMA-IR values above 2. Most of the parameters differed significantly between men and women, as well as between the groups with high and low insulin sensitivity. Body fat mass of the trunk, which was significantly higher in insulin-resistant groups, had a higher correlation with high sensitivity C-reactive protein and hemoglobin levels in women, and alanine aminotransferase and aspartate aminotransferase levels in men. Homozygous minor allele genotype sets of SNPs rs17031578 and rs228669 in the PER3 gene could be more frequently found among women with HOMA-IR values above 2 (p = .014). CONCLUSION: Oxidative stress enhanced by adiposity and iron overload, which may also be linked to NRF2 and PER3-related pathways, is related to IR in adulthood. However, due to the small population size in this study, more research is needed.

Feasibility of combination of Gun-Chil-Jung and cytokine-induced killer cells-based immunotherapy for terminal hepatocellular carcinoma patient: a case report.

Introduction: Terminal-stage hepatocellular carcinoma (HCC) is inoperable and currently has no form of adjuvant therapy. This study examined the anticancer herbal extract Gun-Chil-Jung (GCJ) combined with cytokine-induced killer (CIK)-cell-based immunotherapy as a palliative therapy for terminal HCC. We report the case of an HCC patient with extended overall survival and improved symptoms and tumor marker levels following combination therapy with GCJ and CIK cell-based immunotherapy. Baseline Characteristics: From March to July 2020, a 57-year-old man who had been diagnosed with HCC underwent combination treatment with GCJ and CIK cell-based immunotherapy. By August 2021, he was prescribed GCJ. After treatment, the patient's condition was evaluated with respect to overall survival, tumor markers, symptoms, abdominal computed tomography findings, chest x-ray results, and Eastern Cooperative Oncology Group (ECOG) grade. Results: The patient's overall survival, tumor marker levels, ECOG grade, and symptoms, including ascites, lower limb edema, jaundice, pleural effusion, and fatigue, were largely alleviated. Conclusion: We expect that this combination therapy may be an option for palliative therapy of terminal HCC.

The Clinical Diagnosis-Based Nationwide Epidemiology of Metabolic Dysfunction-Associated Liver Disease in Korea.

BACKGROUND: Although most epidemiological studies have been conducted using a relatively small population or subjects who had medical screenings, the present study aimed to investigate the incidence and prevalence of MASLD (formerly NAFLD) in Korea using nationwide registry data provided by the Health Insurance Review and Assessment Service (HIRA). METHODS: Using nationwide medical records provided by HIRA, we analyzed the entire dataset of patients with MASL (KCD10-K76.0) and MASH (KCD10-K75.8) from 2010 to 2021 and calculated the incidence and prevalence by year, age, and gender. The prevalence and incidence rates were calculated by analyzing the HIRA data covering almost the entire population of Korea for 12 years, from 2010 to 2021, with an average population of 50,856,244 during this period. Statistical analyses included calculating confidence intervals using Ulm's formula and conducting sex- and age-specific analyses with a Cochran-Armitage test for trends. RESULTS: The annual incidence of MASL/MASH increased significantly from 9.71/0.37 in 2010 to 13.95/5.52 per 1000 persons in 2021 (p < 0.01). The annual prevalence of MASL increased from 15.69 in 2010 to 34.23 per 1000 persons in 2021, while the annual prevalence of MASH increased from 0.49 to 9.79 per 1000 persons between 2010 and 2021 (p < 0.01). Regarding the sex-dimorphic feature of MASLD, there was a male predominance in those < 50 years old but a female predominance in those ≥ 50 years old for the incidence and prevalence of MASL and the incidence of MASH. CONCLUSION: The incidence of MASL increased by 3% to 4% every year, while the incidence of MASH increased 14.91-fold from 2010 to 2021. The increasing trend is noteworthy compared with previous reports.

Beneficial effect of Gyejibokryeong-hwan on climacteric syndrome with blood stasis pattern: A randomized, double-blinded, placebo-controlled clinical pilot trial.

Background: Gyejibokryeong-hwan (GBH), a herbal mixture that is widely used for climacteric syndrome, is studied for its efficacy; however, no study evaluated the GBH indication, which is a blood-stasis pattern based on traditional Chinese medicine theory. Methods: This is a randomized, double-blinded, placebo-controlled clinical pilot trial. Fifty subjects with climacteric syndrome were recruited and randomly assigned to GBH group or placebo group. Subjects were administered GBH or placebo granules for 4 weeks followed by 4 weeks of observation period. For the primary outcome, the Menopause Rating Scale (MRS) was evaluated. For the secondary outcomes, quality of life, degrees of abdominal resistance and tenderness, blood-stasis pattern questionnaire and degree of upward movement of Qi were evaluated. Results: After 4-week intervention, the mean change of total MRS score significantly decreased in the GBH group compared to the placebo group (p = 0.037). The quality of life related to physical health (p = 0.008) and blood-stasis pattern (p = 0.018) significantly improved in the GBH group but not in the placebo group. Conclusion: Our findings provide evidence of the feasibility of recruiting subjects with GBH indications and show that GBH may have clinical efficacy for the treatment of menopausal symptoms, especially urogenital symptoms, without any significant adverse events.

Electroacupuncture for Cancer-Related Cognitive Impairment: A Clinical Feasibility Study.

BACKGROUND: Cancer-related cognitive impairment (CRCI) is a significant problem for cancer patients, as the number of cancer survivors experiencing cognitive impairments is increasing in the absence of standard treatment. There have been attempts to improve the cognitive function of patients with cancer using acupuncture; however, no studies have been conducted using electroacupuncture. Thus, we designed a preliminary study to investigate the feasibility of a clinical trial using electroacupuncture in CRCI patients. METHODS: We conducted a single-arm, pilot, clinical trial to investigate the feasibility of a study protocol for further large-scale clinical trials of electroacupuncture in CRCI patients. All participants were treated with electroacupuncture twice a week for 30 minutes at a time, for 8 weeks on acupoints GV20, GV24, EX-HN1, and GB20, HT7, PC6, and KI3. Both subjective and objective outcomes of cognitive function, quality of life (QoL), and psychological factors were measured in all participants at baseline, week 4, 8, and 12. For safety assessment, vital signs, laboratory examinations, and adverse events (AEs) were observed throughout the trial. RESULTS: A total of 12 participants were enrolled at Daejeon and Dunsan Korean Medicine Hospital of Daejeon University from 21 April 2017 to 31 January 2018. After 8 weeks of treatment, electroacupuncture significantly improved both subjective and objective cognitive outcomes, including the perceived cognitive impairments scale of the Functional Assessment of Cancer Therapy-Cognitive Function, QoL scale of the European Organization for Research and Treatment of Cancer Quality of Life Core Questionnaire-C30, Korean version of Montreal Cognitive Assessment, Boston Naming Test, Seoul Verbal Learning Test, and Rey Complex Figure Test. During the entire trial period, 19 AEs were observed, with no serious AEs. Additionally, it was found that all feasibility outcomes, including recruitment, completion, and adherence rates, achieved successful results as the ratio exceeded 0.8. CONCLUSION: Our study results revealed that electroacupuncture improved cognitive complaints in cancer patients, and we expect electroacupuncture to be a safe and effective management therapy for CRCI patients. These feasibility trial results will be used as preliminary data for future randomized controlled clinical trials. TRIAL REGISTRATION NUMBER: Korean Clinical Trial Registry (KCT0002168).

The Role of Epigenetic Changes in the Progression of Alcoholic Steatohepatitis.

Alcoholic steatohepatitis (ASH) is a progression hepatitis with severe fatty liver and its mortality rate for 30-days in patients are over 30%. Additionally, ASH is well known for one-fifth all alcoholic related liver diseases in the world. Excessive chronic alcohol consumption is one of the most common causes of the progression of ASH and is associated with poor prognosis and liver failure. Alcohol abuse dysregulates the lipid homeostasis and causes oxidative stress and inflammation in the liver. Consequently, metabolic pathways stimulating hepatic accumulation of excessive lipid droplets are induced. Recently, many studies have indicated a link between ASH and epigenetic changes, showing differential expression of alcohol-induced epigenetic genes in the liver. However, the specific mechanisms underlying the pathogenesis of ASH remain elusive. Thus, we here summarize the current knowledge about the roles of epigenetics in lipogenesis, inflammation, and apoptosis in the context of ASH pathophysiology. Especially, we highlight the latest findings on the roles of Sirtuins, a conserved family of class-III histone deacetylases, in ASH. Additionally, we discuss the involvement of DNA methylation, histone modifications, and miRNAs in ASH as well as the ongoing efforts for the clinical translation of the findings in ASH-related epigenetic changes.

Risk levels of herb-induced liver injury in Korea: from a meta-analysis.

BACKGROUND: As the use of herbal medicines increased worldwide, there has been concern about the risk of herb-induced liver injury (HILI). Many clinical studies have assessed the risk of HILI in Korea. METHODS: Therefore, we conducted a meta-analysis of the incidence of HILI in Korea, by analyzing nine clinical studies. These involved 8625 participants (3274 males; 5351 females), including 436 outpatients (three studies) and 8189 inpatients (six studies). RESULTS: As a result, the overall incidence of HILI in Korea was 0.49% (95% CI 0.33-0.74%), and it was 0.57% in males and 0.30% in females. We found a similar incidence of HILI in prospective (0.51%) and retrospective (0.50%) studies. The incidence of HILI was higher in inpatients (0.62%) than outpatients (0.03%). CONCLUSION: Although there are limitations regarding study quality and the number of participants, we systematically estimated the risk of HILI in Korea. We anticipate this study would be a helpful information for prescribing herbal medicines and researching the safety of herbs.

Ethyl Acetate Fraction of Amomum villosum var. xanthioides Attenuates Hepatic Endoplasmic Reticulum Stress-Induced Non-Alcoholic Steatohepatitis via Improvement of Antioxidant Capacities.

Non-alcoholic fatty liver disease (NAFLD), including non-alcoholic steatohepatitis (NASH), affects 25% of the global population. Despite the prevalence of NAFLD worldwide, effective therapeutics are currently lacking. Amomum villosum var. xanthioides (Wall. ex Baker) T.L.Wu & S.J.Chen (AX) is a medicinal herb traditionally used for treating digestive tract disorders in countries across Asia. We aimed to examine the pharmacological effects of the ethyl acetate fraction of AX (AXEF) against tunicamycin (TM)-induced ER stress in a NASH mouse model using C57/BL6J male mice. Following TM injections (2 mg/kg), the mice were orally administrated AXEF (12.5, 25, or 50 mg/kg), silymarin (50 mg/kg), or distilled water daily for 5 days, and the outcomes for fatty liver, inflammation, and oxidative stress were measured in serum or liver tissue levels. AXEF drastically attenuated hepatic ER stress-induced NASH as indicated by decreases in lipid droplet accumulations, serum liver enzymes, hepatic inflammations, and cell death signals in the hepatic tissue and/or serum levels. Interestingly, AXEF showed potent antioxidant effects by quenching reactive oxidative stress and its final product lipid peroxide in the hepatic tissue, specifically an increase in metallothionein (MT). To confirm the underlying actions of AXEF, we observed that AXEF increases MT1 gene promoter activities in the physiological levels. Collectively, AXEF showed antioxidant properties on TM-induced ER stress in a NASH mice model through the improvement of MTs.

Moxibustion for treating cancer-related fatigue: A multicenter, assessor-blinded, randomized controlled clinical trial.

Cancer-related fatigue (CRF) is one of the most common chronic symptoms experienced by cancer patients. As moxibustion is a popular traditional therapy for managing fatigue, it can be an alternative strategy to treat CRF as well. Therefore, we rigorously designed a full-scale, multicenter, assessor-blinded, randomized controlled trial to evaluate the efficacy and safety of moxibustion treatment for CRF. Ninety-six subjects suffering from CRF were recruited and randomly assigned to moxibustion group, sham moxibustion group, or usual care group. Both the moxibustion group and the sham group received moxibustion treatment for 8 weeks and the usual care group did not. Brief fatigue inventory (BFI) score and Functional Assessment of Cancer Therapy-Fatigue score were used to assess CRF at baseline and weeks 5, 9, and 13. Questionnaires for the assessment of cognitive impairment, quality of life, and Cold-Heat and Deficiency-Excess patterns were also evaluated. BFI scores significantly decreased in moxibustion group compared to the usual care group (mean difference of -1.92, p < 0.001 at week 9 and mean difference of -2.36, p < 0.001 at week 13). Although the sham group also showed significant improvement during the treatment period, only the moxibustion group showed improvement after 4 weeks of follow-up period (mean difference of -1.06, p < 0.001). There were no serious adverse events. Our findings confirmed the efficacy and safety of moxibustion for CRF compared to usual care. We also found that moxibustion has a prolonged treatment effect during 4 weeks of follow-up period.

Efficacy of a Traditional Herbal Formula, Banha-Sasim-Tang in Functional Dyspepsia Classified as Excess Pattern.

This study evaluated the efficacy and safety of Banha-sasim-tang (BST) in patients with functional dyspepsia (FD). BST (Banxia-xiexin-tang in traditional Chinese medicine and Hange-shashin-to in Kampo medicine) is traditionally prescribed for the treatment of dyspepsia with epigastric stiffness and gastric fullness in China, Japan, and Korea. Patients with FD were randomly administered an oral dose (10 g) of BST syrup or placebo, twice a day for 4 weeks. The primary outcome was the symptom checklist part of the Nepean dyspepsia index (NDI). The secondary outcomes were the quality of life (QoL) part of the NDI, functional dyspepsia-related QoL (FD-QoL), and visual analog scale (VAS). A total of 60 patients with FD were screened, and 50 were randomized into BST group (n = 25) and placebo group (n = 25). Two patients in the placebo group withdrew before the start of the treatment. Administration of BST syrup resulted in improvement in the symptom-related NDI score in the BST group compared with that in the control group; however, the difference was not significant. BST syrup significantly improved "fullness after eating" index of NDI at follow-up time point (2.88 ± 2.65 vs 4.78 ± 2.69, p = 0.0081). In the total score of the QoL section of the NDI and FD-QoL scales, there was no significant improvement in the BST group compared to that in the placebo group. With regard to improvement in overall FD symptoms, the VAS scale showed improvement in both groups, but the difference was not significant. Interestingly, follow-up investigation showed a significantly beneficial effect of BST on FD symptoms, when compared to placebo. Significant improvement observed in VAS score (39.60 ± 22.29 vs 52.17 ± 20.55, p = 0.048). This indicated that the effect of BST lasted even after the completion of the medication regimen. Overall, our data suggest that while BST showed no significant improvement in the symptom-related NDI score and the QoL related scores in NDI and FD-QoL after 4 weeks of treatment, it effectively improved the VAS score and fullness after eating-related symptoms in the follow-up visit.

Anti-hepatofibrotic effects of CGX, a standardized herbal formula: A multicenter randomized clinical trial.

BACKGROUND: Chunggan extract (CGX) is an herbal formula used for the treatment of chronic liver disease in traditional Korean medicine. Many preclinical studies have suggested its therapeutic or preventive effects on liver fibrosis. To evaluate the efficacy and safety of CGX, we conducted a randomized controlled clinical trial of CGX in patients with liver fibrosis diagnosed by Fibroscan. METHODS: We enrolled 67 subjects at two hospitals with chronic liver disorders with a 5.5 ≤ liver stiffness measurement (LSM) score ≤ 16 kPa. Subjects were randomly assigned at a 1:1:1 ratio with stratification (with/without concomitant use of antivirals) and orally administered CGX (1 g or 2 g) or placebo twice daily for 24 weeks. The end point was the change in instantaneous elasticity of the liver assessed by Fibroscan before and after treatment. RESULTS: LSM scores were significantly decreased in both the CGX1 g (2.5 ± 1.7 kPa, p < 0.01) and CGX2 g (1.9 ± 2.0 kPa, p < 0.05) groups compared to the placebo (0.6 ± 1.6 kPa) group. The change was also significant in 35 subjects without concomitant use of antiviral agents in the CGX1 g group (placebo 0.1 ± 1.4 kPa vs. 2.7 ± 1.6 kPa, p < 0.01) but not in those with concomitant antiviral use (p > 0.05). No notable adverse events were present. CONCLUSION: CGX appeared to have a pharmacological effect against liver fibrosis. Further studies to confirm the results are needed in the future using a larger sample size.
